Hydraulic System
Maintenance

Hydraulic System Safety

Seek immediate medical attention if fluid is injected
into skin. Injected fluid must be surgically removed
within a few hours by a doctor.
Ensure that all hydraulic-fluid hoses and lines are
in good condition and all hydraulic connections
and fittings are tight before applying pressure to
the hydraulic system.
Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure hydraulic
fluid.
Use cardboard or paper to find hydraulic leaks.
Safely relieve all pressure in the hydraulic system
before performing any work on the hydraulic
system.
Hydraulic Fluid
Specification
The reservoir is filled at the factory with
high-quality tractor transmission/hydraulic fluid. The
recommended replacement fluid is as follows:
Toro Premium Transmission/Hydraulic Tractor
Fluid (Available in 19 L (5 gallon) pails or 208 L (55
gallon) drums. See the Parts Catalog or your Toro
Distributor for part numbers).
Alternate fluids: If the Toro fluid is not available,
Mobil® 424 hydraulic fluid may be used.
Note:
Toro will not assume responsibility for damage
caused by improper substitutions.
Many hydraulic fluids are almost colorless, making
it difficult to spot leaks. A red dye additive for the
hydraulic system oil is available in 20 ml (2/3 fl oz)
bottles. One bottle is sufficient for 15 to 22 L (4 to 6
US gallons) of hydraulic fluid. Order Part No. 44-2500
from your authorized Toro distributor.
